i was wondering what type of 360 heads should i put on my 318? i can get a set of rebuilt 360(78volare) non smog heads from advance for 200 wonder if these would be a good choice? and help would be great

 

If you plan on adding a cam or the cam is bigger then stock, i would thing the 360 head would be a good idea. However you cant install you 318 manifold on them 360 head.......It won't fit. but any 340/360 will work just fine.

 

why do you say this? any 318 manifold from 67 on (non magnum) will fit a 340 or a 360. with those heads you gain bigger valves and lose a little bit of compression

 

It was many a years ago and what i tried was kinda backward from my statement above

I tried to install factory 340 alu intake manifold(LD340) onto my 318. it would not physically fit as the manifold wouldn't go down far enough to start the bolts. I used a rubber mallet, stood on it.........It would not fit!

After market Manifold have a slotted bolt holes in them and will fit the slight difference between the 273/318 and the 340/360.

The block deck Height Is a little bit taller on the 340/360 block causing this problem.
As fare as the power added from early 360 heads on a 318 i never did. so i real wouldn't know
Or maybe it intake surface that different tween the two heads, All i know is that it would not fit! but the after market dual plain i installed did.(dual port sp2p...I think.)

 

i have a cast iron 360 manifold that was already ported out and i had on the 318 and it bolted up just fine but im probaly goin to buy a m1 dual plane intake. and its getting a bigger cam put in it. the Jheads are hard to get thats why i was asking about the 78 360 heads so it looks like so far for 200$ its my best bet just goin to do some portin on it.

actually the block height is the same on all four blocks 273,318,340 all share the crank and stroke (besides cast and forged) the 360 is the only oddball. (besides me) the only heads i know that are a bit different are the 64-67 273. the intake side is slightly a different angle. on to heads x heads are the best stock head you can get 202 intake 1.60 ex. all other 340 and 360 heads were 1.88 1.60 W-2was a good head also

 

Was the 360 intake bolted to the stock 318 heads????????

If it was then i must have done something wrong, but I tried ever thing. would not fit, put my stock 318 manifold on and it bolted right up.
It is vary possible, that i did something wrong, as it was when i was a younger pup some 20 years ago

My buddy, at that time had a 68 dart with a 318 and bolt on some J heads and intake, with no problem.........so i have ASSumed that the 318 head was my problem.......hmmmmmm

 

all la heads bolt to all la as i said above (but i dont know about magnum) and other way around...... but some 273s and all w-2 heads.

 

If your 318 is all stock (pistons,cam,etc.) I wouldn't advise this. with the 360's larger combustion chamber, you will lose compression, & 318's are already pretty low! Your best bet would be a set of "high swirl" heads off of a 87-89 318. I don't have the casting #s handy, but they should be good for 25-30 more hp.

 

its been bored .30 over , has forged pistons,crank and rods. just got to choose a cam and get the heads, that's why i was asking about the heads. already have intake,carb and headers

 

Do you know what compression ratio the slugs are supposed to be with stock heads? and what year? that way i can roughly tell you what compression you will be at with the 360 heads. and that will aid in cam selection

 

sry it took my so long ive been out of town. the piston are 10 to 1

 

I tryed to put a 360 intake on my 318, but the EGR was completely different. The 318 had a sideways C shape port and the intake had a rectangle. So now i have to stick to my 2 barrel till I can get some new heads. Are the Holley 500's any good?
